There were Senate endorsements galore in GOP circles today, with a few of the highest profile conservative Senators coming out in support of candidates locked in tough GOP primaries. Here’s a quick rundown of what happened:

Texas Solicitor General Ted Cruz picked up an endorsement from Sen. Tom Coburn (R-Okla.). Alluding to one of the most intense rivalries in college football (between the University of Texas and the University of Oklahoma), Coburn wrote in a statement, “Oklahoma and Texas may have our friendly rivalry, but when it comes to fighting for limited government, I’m proud to endorse my neighbor across the Red River.”

Along with Sen. Ron Johnson (R-Wis.), Coburn also gave his nod to businessman John Brunner, one of three contenders for the GOP nomination in the Missouri Senate race. “John Brunner will be a force for fiscal conservatism in the U.S. Senate, and I am proud to endorse his candidacy,” Coburn said in a statement released by the Brunner campaign. Earlier this year, Sen. Mike Lee (R-Utah) endorsed former state Treasurer Sarah Steelman, another GOP contender hoping to take on vulnerable Sen. Claire McCaskill (D-Mo.) in November.
